<p>PURPOSE:To shorten the time for building three members so as to improve work efficiency by engaging the first member with the second member, engaging the third member with the first or second member, and screwing the third member to the second or first member to fix the first to third members. CONSTITUTION:In the case of connecting three members of a main valve 108, pilot valve 110 and a fixed cap 112, first the third engaging part 32 of the pilot valve 110 is fitted into a through hole 16 of the first engaging part 18 of the main valve 108, to closely attach wall surfaces 14, 30 of both the valves 108, 110. Next while engaging the second engaging piece 42 of the fixed cap 112 with an engaging groove 34 of the main valve 108, pillar-shaped protrusion 38 with an engaging hole 22 and further the first engaging valve 110 with a back surface of the first wall surface 14 of the main valve 108, wall surfaces 36, 20 of both the fixed cap 112 and the main valve 108 are closely attached. Thereafter, a bolt, inserted through the fixed cap 112, is screwed in the screw hole 24 of the main valve 108, and by tightening this bolt, the three members are fixed together.</p> |
